可以的。。给你推荐一篇文章你看看http://blog.sina.com.cn/s/blog_59fa1c660100ctir.html?retcode=0
 如果没有看懂，我原来做过把很多execl打包载的有源码 可以给你参考哈 msn:[email protected]

}
用ICSharpCode.SharpZipLib.dll
加上上面的类
调用    public string Compress(string RootPath, List<string> filename)
    {
        //   压缩    
        string Name = DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".zip";
        string FileName = Path.Combine(RootPath, Name);
        string topPath = Path.GetPathRoot(RootPath);        SharpZipLibHelper.ZipFile(RootPath, filename.ToArray(), FileName, 7, "", "");        return FileName;
    }
